Size and fit

The Merrell Hydrotrekker is a low-top hiker for men and women that is available in medium-widths. It has a soft, flexible upper that promotes freedom of movement and a lace-up closure for a custom fit. There's also a pull loop at the back for easy on and off.


This water-friendly hiker from Merrell has the M Select WET GRIP outsole which features multidirectional lugs that bite into wet and dry surfaces, including rocks, gravel, sand, and dirt. There are also water channels in various zones for quick dispersal of water. This rubber outsole is slip-resistant, which is very important to prevent slipping on slick rocks and wet surfaces.

Such outsole has a relatively shallow depth (3.5) so it is ideal for hard surfaces, such as rocks, packed dirt, and concrete.


The Hydrotrekker has a midsole made of compressed ethylene vinyl acetate (EVA). It's a foam-like material that is lightweight, flexible, and cushions the foot nicely. The major advantage of EVA over other shock-attenuating materials is its lightness. Light hiking footwear is great for day hiking when you're not carrying a heavy backpack as it promotes freedom of movement without slowing you down. Unique to the Hydroktrekker midsole is the presence of holes and ports that don't just channel water out but also promote ventilation so the shoe dries quickly.


Featuring a fully synthetic upper, this hiking shoe dries easily once exposed to water. The mesh lining delivers utmost breathability. Giving support and structure to the shoe are the synthetic overlays. Also completing the upper is a webbing lacing system that provides a secure fit that can be adjusted whenever needed.
